OAS-1

The device to measure the oxygen concentration by sampling the atmosphere such as nitrogen reflow equipment.

- Requires no calibration with reference gas before using the analyzer.
- Features longer sensor service life than other galvanic battery type sensors.
- A PC communication output port (RS-232C) as a standard feature.
